what are some functioning MMS APN settings for the Nokia Lumia 1520

With the recent upgrade to Windows 10 Mobile I have found that my MMS no longer works. I have a Straight Talk SIM card from a BYOP kit that has worked for a year or so until this upgrade. I have tried several things I have found online with no success. If anyone has the correct settings or any help please respond. I'm kinda at my wits end.

set up the APN as tfdata.
WAP Gateway (URL) value should be mms3.tracfone.com.
WAP Gateway Port value is 80.
MSSC (URL) value is http://mms-tf.net.
MMSC Port value is 80.
Username and Password should be blank.
IP type is IPv4
